2012-04-17usb_packet_set_state: handle p->ep == NULLGerd Hoffmann1-6/+11
usb_packet_set_state can be called with p->ep = NULL. The tracepoint there tries to log endpoint information, which leads to a segfault. This patch makes usb_packet_set_state handle the NULL pointer properly. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb-host: add property to turn off pipeliningGerd Hoffmann1-1/+9

2012-04-17Add bootindex support to usb-host and usb-redirGerd Hoffmann2-0/+6
When passing through a usb pendrive seabios will present it in the F12 boot menu and will happily boot from it. This patch adds bootorder support so you can even make it the default boot device. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb-uhci: queuing fixGerd Hoffmann1-3/+10
When we queue up usb packets we may happen to find a already queued packet, which also might be finished at that point already. We don't want continue processing the packet at this point though, so lets just signal back we've found a in-flight packet when in queuing mode. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb-uhci: stop queue filling when we find a in-flight tdGerd Hoffmann1-0/+3
Not only QHs can form rings, but TDs too. With the new queuing/pipelining support we are following TD chains and can actually walk in circles. An assert() prevents us from entering an endless loop then. Fix is easy: Just stop queuing when we figure the TD we are about to queue up is in flight already. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-17usb/vmstate: add parent dev pathGerd Hoffmann3-1/+25
... to make vmstate id string truely unique with multiple host controllers, i.e. move from "1/usb-ptr" to "0000:00:01.3/1/usb-ptr" (usb tabled connected to piix3 uhci). This obviously breaks migration. To handle this the usb bus property "full-path" is added. When setting this to false old behavior is maintained. This way current qemu will be compatible with old versions when started using '-M pc-$oldversion'. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2012-04-16qemu-timer.c: Remove 250us timeoutsPeter Portante1-5/+5
Basically, the main wait loop calls qemu_run_all_timers() unconditionally. The first thing this routine used to do is to see if a timer had been serviced, and then reset the loop timeout to the next deadline. However, the new deadlines had not been calculated at that point, as qemu_run_timers() had not been called yet for each of the clocks. So qemu_rearm_alarm_timer() would end up with a negative or zero deadline, and default to setting a 250us timeout for the loop. As qemu_run_timers() is called for each clock, the real deadlines would be put in place, but because a loop timeout was already set, the loop timeout would not be changed. Once that 250us timeout fired, the real deadline would be used for the subsequent timeout. For idle VMs, this effectively doubles the number of times through the loop, doubling the number of select() system calls, timer calls, etc. putting added scheduling pressure on the kernel. And under cgroups, this really causes a big problem because the cgroup code does not scale well. By simply running the timers before trying to rearm the timer, we always rearm with a non-zero deadline, effectively halving the number of system calls.

2012-04-16Kick io-thread on qemu_chr_accept_inputJan Kiszka1-0/+1
Once a chr frontend is able to receive input again, we need to inform the io-thread about this fact. Otherwise, main_loop_wait may continue to select without the related backend file descriptor in its set. This can cause high input latencies if only low-rate events arrive otherwise.

2012-04-15w64: Fix type cast in os_host_main_loop_waitStefan Weil1-1/+1

Replace all type casts to 'long' or 'unsigned long' by 'intptr_t' or 'uintptr_t'. For type casts which are only used to extract the lower bits of an address or to modify those bits, signedness does not matter. There I always use 'uintptr_t'. Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15softmmu: Use uintptr_t for physaddr and rename itStefan Weil1-9/+6
Variable physaddr is a host address which should be represented by data type 'uintptr_t'. This is needed for w64 and changes nothing for other hosts. v2: Rename physaddr -> hostaddr (suggested by Blue Swirl). Signed-off-by: Stefan Weil <sw@weilnetz.de>
2012-04-15w64: Fix struct CPUTLBEntryStefan Weil1-5/+5

2012-04-15w64: Fix definition of setjmpStefan Weil1-0/+9
The default definition of setjmp which is implemented in MinGW-w64 cannot be used with programs like QEMU which call longjmp from code without structured exception handling (SEH). This code therefore disables stack unwinding. We could also implement SEH for QEMU's generated JIT code, but that is much more difficult. Stack unwinding would also cost execution time.

2012-04-15w32: Move defines for socket specific errors to qemu-os-win32.hStefan Weil3-18/+26

2012-04-15tcg/i386: Add support for w64 ABIStefan Weil1-11/+28
w64 uses the registers rcx, rdx, r8 and r9 for function arguments, so it needs a different declaration of tcg_target_call_iarg_regs. rax, rcx, rdx, r8, r9, r10 and r11 may be changed by function calls. rbx, rbp, rdi, rsi, r12, r13, r14 and r15 remain unchanged by function calls.

2012-04-15pseries: Fix reset of VIO network deviceDavid Gibson1-3/+11
Currently, the PAPR VIO network device does not have a reset handler.

2012-04-15pseries: Correctly use the device model reset hooksDavid Gibson2-4/+9
Recently we added code to properly clean away VIO CRQs on reset However, this directly uses qemu_register, rather than the existing device model reset callbacks.

2012-04-15pseries: Fix RTAS based config accessDavid Gibson1-38/+79
On the pseries platform, access to PCI config space is via RTAS calls( which go to the hypervisor) rather than MMIO. This means we don't use the same code path as nearly everyone else which goes through pci_host.c and we're missing some of the parameter checking along the way. We do have some parameter checking in the RTAS calls, but it's not enough. It checks for overruns, but does not check for unaligned accesses, oversized accesses (which means the guest could trigger an assertion failure from pci_host_config_{read,write}_common(). Worse it doesn't do the basic checking for the number of RTAS arguments and results before accessing them. This patch fixes these bugs. Cc: Michael S.
